I have had a leak at the lid of the oil filter housing for some time. It has gotten progessivly worse, to the point were it is now leaving a puddle on the driveway. I replace my filter and rubber o-ring at the same time. I use aftermarket filters and o-rings from Napa and such. I believe the lid is on tight enough, do you think the aftermarket o-ring is inferior to OEM and allowing the leak?

Is this a common problem with these units?
